As stated on the back of the W-2 -
Keep Copy C of Form W-2 for at least 3 years after the due date for filing your income tax return. However, to help protect your social security benefits, keep Copy C until you begin receiving social security benefits, just in case there is a question about your work record and/or earnings in a particular year.
TurboTax does not have a copy of the W-2 or Form 1099. It would have W-2 and Form 1099 worksheets that included the tax data from the forms that were entered. The worksheets would be included in the PDF of the tax return in the tax year the return was completed.
Copies of a Form 1099 would have to obtained from the issuer of the form.
If you cannot obtain the W-2 from your employer, then for a fee you can get a complete copy of a W-2 from the Social Security Administration - https://faq.ssa.gov/en-us/Topic/article/KA-02501

If you are getting a refund, there is no penalty for filing late. If you owe tax due, then file and pay the amount due as shown on the Form 1040, but expect a bill later from the IRS for the penalty and interest you will owe. Only the IRS will calculate this—TurboTax will not calculate it.
